Flushing the MGB cooling system

When’s the last time you managed to get your MGB’s cooling system flushed for all of $6.00? Granted, at this time gas was likely $.35 per gallon or so and you could probably buy a fairly nice house for maybe $40,000. Well, 3 years after being purchased the lucky MGB GT had this service performed on February 4, 1971 at some unknown location, presumably in Pasadena.
